configuration of the Teradek product based on the Huawei modem's mode (Hi-Link / Ethernet, versus non-Hi-Link as a serial or composite device)

We have confirmed support for the E3276-s150 and the E3276-s500. Note that there are several variants of the E3276 (see here for a partial listing of models).

These different models may identify themselves differently in software, which would mean that if they didn't work in the current firmware they could need support added in a future firmware update.

In addition to the model variations at a hardware level, there are at least two software differences in how the modems identify themselves to computers:

* as a Serial device, corresponding to the Custom -> GSM setting

* as a Composite or Ethernet device, corresponding to the Custom -> Composite or Custom -> Ethernet setting; this variation is sometimes branded as a "HiLink" device by Huawei

they may also work in Auto mode

If the E3276 firmware version starts with a "21" then it should act as a serial device; if it starts with a "22" then it should use the Composite or Ethernet settings.

GSM configuration

If the firmware on the modem starts with "21", then you would need to use the Custom -> GSM setting with the APN assigned to the mobile carrier's account. The "CID" value should not need to be changed and would be left at 1.

Composite / Ethernet configuration

If the firmware on the modem starts with "22" then you can try either the Custom -> Composite or the Custom -> Ethernet setting.

Comments

Has anyone had issues where the latency on the hi-link version of the dongles have massive ping times and keep suspending (assuming the suspending is due to the being large ping times greater then the buffer)

I have witnessed up to 35seconds. I have a screen print where the dongles go into suspended state on a regular basis

We trying to find out what is causing it but not really getting anywhere

The firmware on the dongles starts with 22 and the are branded as Hi link

The dongles are a mix of UK networks and no 2 networks are next to each other and also extended away from each other to make sure it was not interference caused by other dongles.

Just not sure why we are getting this regular packet drop.

The dongles are discovered as Custome > ethernet as recommended due to them working in a router mode. Have been looking into flashing them into modem only mode but with no real success
